If the monitor is switched off or another video source is selected, FreeBSD for some reason disables screen output on the system, so when switching the monitor on again or selecting the previous video source, screen output is no longer present and the monitor can't detect any signal from the FreeBSD system, exactly as if the system was shutdown. The only way to restore screen output is by rebooting the system with the monitor switched on, and I don't think that rebooting the system everytime we need to do work from the console is a satisfying solution. I can rule out hardware problems as various Linux distributions have been installed on the same setup and the problem described is not present, the behaviour is only seen with FreeBSD. I would really appreciate any suggestions, hints, comments or anything else that could point me in the direction of a solution, as this problem is driving us nuts.
